ZAPP WIRELESS SYSTEM

STANDARDS AND NORMS

The ZAPP System complies with CE and EN 300 220-1 and EN 301 489-1.

Use in Combination with Legacy Devices

The W7070A2000 ZAPP Wireless Receiver is suitable for use only with the T7270A2001, T7270A2019, T7270B2009 ZAPP Wireless Wall Modules and the RT7070A2008 ZAPP Wireless Handheld Remote Control. It cannot communicate with (but is likewise unaffected by) legacy devices (e.g. the T7270A1001, T7270A1019, T7270B1009, or the RT7070A1008).

APPLICATION STEPS

Overview

Steps one through seven describe the engineering. These steps are guidelines intended to aid understanding of the product options, bus arrangement choices, configuration options and ZAPP's role in the overall EXCEL 5000® System architecture.

Step 1: System Planning

Plan the use of ZAPP according to the required functionality and the sensor or actuator usage.

When planning the system layout, consider potential expansion possibilities to allow for future growth.

Step 2: Range of RF Transmission

Because of interference from other devices and the building structure, it is not possible to exactly define the wireless transmission range.

General Guideline

The max. distance between the W7070A2000 and ZAPP room units should be less than 30 meters, and there should be no more than two walls between the W7070A2000 and ZAPP room units. See W7070A2000 Receiver Installation Instructions (EN1B-0396GE51) for details on installing wireless systems.

Step 3: LonWorks Communications

The W7070A2000 utilizes a free-topology transceiver (FTT10A) Link Power compatible LONWORKS® network that allows daisy-chain, loop, and star network configurations or any combination thereof (see also Excel 50/500 LONWORKS Mechanisms Interface Description, Product Literature No.:

EN0B-0270GE51, for a complete description of possible layouts and wiring details, including max. lengths).

Depending upon the LONWORKS ® network configuration used, one or two termination modules may be required (see Fig. 2). Different connections to the termination module are necessary, depending upon whether it is used in a singleor double-terminated network configuration.

Fig. 2. Termination module connection (daisy-chain network configuration shown)

NOTE: The LONWORKS ® network is insensitive to polarity, eliminating installation errors due to miswiring

Wire the W7070A2000's LonWorks ® communications network using level IV 22 AWG or plenum-rated level IV 22 AWG non-shielded, twisted pair, solid conductor wire.

IMPORTANT!

Do not bundle wires carrying field device signals or LonWorks communications together with high-voltage power supply or relay cables. Specifically, maintain a min. separation of 80 mm between such cables. Local wiring codes may take precedence over this recommendation.

IMPORTANT!

Try to avoid installing in areas of high electromagnetic noise (EMI).

The LonWorks network is connected to terminals 5 and 7. Terminals 6 and 8 may be used to connect further devices to the same LonWorks network.

Step 4: Power Supply

IMPORTANT!

Local wiring guidelines (e.g. VDE 0100) may take precedence over recommendations provided in these recommendations.

All wiring must comply with applicable electrical codes and ordinances. Refer to job or manufacturers’ drawings for details. Use a min. of 18 AWG (1.0 mm2) and a max. of 14 AWG (2.5 mm2) for all power wiring.

The power supply (24 Vac [±20%], 50 or 60 Hz) is connected to terminals 1 and 3. Terminals 2 and 4 may be used to connect further devices to the same 24 Vac power supply.

Step 5: Configuring the W7070A2000

The W7070A2000 is configured using a plug-in which may be used with CARE or any other LNS-based tool such as LonMaker™ for Windows.

After configuring (commissioning), the W7070A may initially display invalid values on its LONWORKS interface. You can force an update (i.e. by manipulating the adjustment dial of the ZAPP Wall Modules or the setpoint key of the ZAPP Handheld).

If the factory pre-configuration already fits your needs, configuration is not necessary (see Appendix).

NOTE: If communication between the W7070A2000's neuron processor and its co-processor is interrupted, the W7070A2000 will display an error message (see Fig. 4). This will occur e.g. when an unconfigured W7070A2000 is powered up.

To resume normal operation, set the W7070A2000 to "configured online"

room unit, the W7070A2000 will then recognize commands it receives from them.

Teaching-in can be done as described in the following sections or by using the plug-in.

NOTE: When using the plug-in to teach in the ZAPP room units, it is necessary that you stop teaching in a given ZAPP room unit before starting to teach in the next ZAPP room unit. This is because the W7070A2000 will remain in the teach-in mode for 5 minutes, and you may accidentally teach in the same ZAPP room unit again if you do not wait sufficiently long before teaching in the next ZAPP room unit.

1) Enabling the Teach-In Mode

Press the button on the W7070A2000 for at least two seconds. "TEACH" and “1” is displayed, thus indicating that the W7070A2000 is now in the teach-in mode for room 1.

NOTE: If you enter no input within 3 minutes, the W7070A2000 will revert back to the normal mode.

2) Selecting a Unique Number

You must now assign a unique number (1 through 8) to the given ZAPP room unit by pressing the button on the W7070A2000 as many times necessary.

Step 6: Teach-In Procedure

Teach-in is a procedure required to allocate ZAPP room units located in the various different rooms to the W7070A2000. Up to eight rooms, each containing a ZAPP room unit, can be allocated to a single W7070A2000. After successful completion of the teach-in procedure for each individual ZAPP

unique number

Fig. 7. Assigning unique number

Since the RT7070A2008 Wireless Handheld is not equipped with a temperature sensor, in order for the W7070A2000 to receive information on room temperature, you must assign the same unique number to both the RT7070A2008 in a particular room and the T7270A2001 or T7270A2019 located in that same room.

The W7070A2000 is now ready to receive teach-in messages from the ZAPP room units.

3) Teaching-In a ZAPP Room Unit

3a) Teaching-In an RT7070A2008

On the RT7070A2008, press "UP, "B," and "OK" simultaneously to send the teach message to the W7070A2000.

If the teach-in was successful, the W7070A2000 will display the corresponding texts ("PRESENT" and "OK").

The appearance of the symbol indicates that the ZAPP room unit which has been taught-in is an RT7070A2008.
